Definitions
- a homogeneous composition and process is provided for an alloy gum extracted from seeds of the genus Cassia which will form a clear, stable colloidal solution in an aqueous medium.
- U. S. Patent No. 4,661,475 discloses that galactomannan gums are useful substances which are added to an aqueous medium in order to achieve the desired consistency or viscosity. Like virtually all natural gelling agents and thickeners with the exception of gelatin, galactomannan gums are derivatives of polysaccharides, that is, high-polymeric carbohydrates.
- Polysaccharides are water-soluble or strongly swellable substances, and include compounds which in aqueous systems give colloidal, more or less highly viscous solutions or dispersions having plastic or pseudo-plastic flow and having functional properties such as a thickening action, water-binding capacity, stabilization of suspensions and emulsions in polyphase systems, and gel formation.
- Galactomannans like the starches, are vegetable reserve polysaccharides. They occur in the endosperm cells of numerous seeds of legumes.
- the collective term “galactomannan” or “polygalactomannan” comprises all polysaccharides which are built up of galactose and/or mannose residues and in addition can also contain minor amounts of other sugar residues.
- galactomannans There is a relatively large number of galactomannans, which vary in composition depending on their origin. The materials principally occur in the endosperm portions of legumes such as guar, locust bean, tara, honey bean, flame tree and sesbania.
- Galactomannans are built up of a linear mannose chain which itself is built up of mannopyranose rings linked by ⁇ -(1,4)-glucoside bonds. To these rings are attached, as branches, isolated galactopyranose residues by ⁇ -(1,6)-glucoside bonds.
- Galactomannan gums when dried and ground to a powder are well known to be particularly difficult to disperse into an aqueous solution and instead clump together, according to U.S. Patent No. 3,80 ⁇ 8,195.
- locust bean gum, guar gum and tara gum have been the principal galactomannan gums of commerce.
- Cassia species contain potentially useful endosperm galactomannans analogous to locust bean gum, tara gum, and guar gum.
- Cassia gum like locust bean gum, exhibits gel strength synergy with carrageenan, xanthan, and agar according to U.S. Patent 4,661,475.
- the Cassia gum when dried to a solid fails to redissolve completely in water. When the solid is dispersed in water and heated, a portion will redissolve, but a substantial part will only imbibe water and swell. The mixtures may sometimes appear to be clear solutions until examined closely, and on standing the solutions become cloudy.
- Cassia gum can be extracted from Cassia seeds, preferably the meal or solvent-washed meal of the ground seeds, by use of water or aqueous solutions at a variety of temperatures, reagent concentrations, and the like. These freshly extracted solutions do not contain insoluble, swollen particles and do not develop a haze on standing. The residual insolubles can be removed, by conventional methods, such as centrifuging and/or filtering. The resulting solutions, when processed to a solid state, fail to fully dissolve. Dry mixing ground Cassia gum with other regents (like sorbitol, sucrose, inorganic salts, or other gelling and thickening agents) yields a two phase mixture from which the Cassia gum fails to dissolve in an aqueous medium completely.
- regents like sorbitol, sucrose, inorganic salts, or other gelling and thickening agents
- the resulting aqueous composition appears to be a suspension or dispersion of insoluble swollen particles within the solution which do not eventually dissolve.
- the resulting aqueous composition if originally clear, forms a haze on standing. This haze is accelerated by heating and appears to be caused by a white film surrounding the insoluble, swollen particles. This haze makes it undesirable for dried Cassia gum formulations to be employed when product clarity is important. Further, the insoluble portion of the Cassia gum is no longer available to gel or impart viscosity to an aqueous medium.
- EP-A-0139913 discloses gelling agents and thickeners based on Cassia-galactomannans and comprising a synergistic mixture of (a) Cassia-galactomannan and (b) carrageenan, agar and/or xanthan. However, the components are present as physical mixtures and are not coprecipitated to form a solid alloy gum.
- the present invention provides a solid alloy gum composition as defined in claim 1 of the accompanying claims, a process for its preparation as defined in claim 4, and a process for its rehydration as defined in claim 13.
- the alloy gum composition is prepared by extracting seeds of the genus Cassia with an aqueous medium to form a soluble extract portion and an insoluble residue portion, optionally separating the soluble extract portion from the insoluble residue portion, incorporating into the soluble extract portion a solubilizing quantity of said gelling and thickening agent and coprecipitating therefrom an alloy gum composition which forms on rehydration a substantially clear, stable colloidal aqueous solution, optionally containing the insoluble residue portion.
- inert materials into the alloy gum composition such as gelling or thickening agents which do not form an alloy gum when coprecipitated with a Cassia seed extract or other inert materials, such as the insoluble residue portion of extracted Cassia seeds.
- inert materials such as gelling or thickening agents which do not form an alloy gum when coprecipitated with a Cassia seed extract or other inert materials, such as the insoluble residue portion of extracted Cassia seeds.
- inert materials such as gelling or thickening agents which do not form an alloy gum when coprecipitated with a Cassia seed extract or other inert materials, such as the insoluble residue portion of extracted Cassia seeds.
- the insoluble residue portion prior to coprecipitating the alloy gum composition.
- the scope of the present invention is intended to include the alloy gums and the process of producing them whether or not inert materials are incorporated therein.
- gelling and thickening agent includes polysaccharide gums, hydrocolloids, which are compounds yielding a gel on combination with water, and/or compounds which in aqueous systems give colloidal, more or less highly viscous solutions or dispersions having plastic or pseudo-plastic flow including properties such as a thickening action, water-binding capacity, stabilization of suspensions and emulsions in polyphase systems, and gel formation.
- solution is a homogeneous composition and includes a gel or colloidal dispersion in a medium which does not contain a substantial quantity of a persistently insoluble polysaccharide gum portion and which does not form a haze on standing.
- homogeneous as used herein comprises a single phase of matter which is uniform in chemical composition.
- a homogeneous composition includes alloy gums comprising two or more chemically different compounds such as a galactomannan gum and a xanthan gum as distinguished from a two phase physical mixture of a galactomannan gum and a xanthan gum.
- Water-soluble Cassia gum can be extracted with an aqueous medium by conventional methods, preferably from the meal or solvent-washed meal of ground Cassia seeds.
- the extraction temperature can range from the freezing point to the boiling point of the aqueous medium. Elevated temperatures of 40 ⁇ °C to 10 ⁇ 0 ⁇ °C are desirable.
- the residual insolubles can be separated by centrifuging, filtering or the like.
- the aqueous medium may comprise water or aqueous solutions containing salts or other compounds.
- Any seeds of the genus Cassia may be employed as the source of Cassia gum, Cassia tora and Cassia occidentalis are preferred because of their commercial availability.
- Cassia meal can also be coextracted with gelling and thickening agents in the crude form.
- Cassia meal can be coextracted with locust beans or an alkali-modified ground seaweed powder which releases carrageenan when mixed with heated aqueous solutions.
- At least one gelling and thickening agent may be incorporated into the aqueous medium prior to, during or after extracting the Cassia gum from the Cassia seed.
- a gelling and thickening agent selected from carrageenan, furacellaran, agar, agarose, agaropectin, dextran, xanthan, algin, carboxymethylcellulose, gellan, low methoxyl pectin, hydroxyethylcellulose, locust bean gum, deacetylated chitin, polyacrylamide, polyethylene glycol and polyvinyl alcohol is incorporated into the extract of the Cassia seed meal prior to coprecipitating the aqueous extract, the resulting Cassia gum composition will usually fail to redissolve to form a solution.
- the exact proportion of Cassia gum and the gelling and thickening agent employed in the present invention can be varied over a wide range generally it requires at least one part by weight of the gelling and thickening agent to about four parts by weight Cassia gum to be a solubilizing quantity. If less than 0 ⁇ .2 parts by weight of Cassia gum is employed per part by weight of the gelling and thickening agent, the composition may be too reduced in Cassia gum to exhibit sufficient synergy to be considered a Cassia alloy gum composition. Other gums and hydrocolloids such as guar gum and tara gum can be incorporated into the alloy gum composition but do not appear to enhance the solubilizing of the Cassia gum composition.
- One unexpected benefit of the Cassia alloy gum compositions of the present invention is that many of the gelling and thickening agents, and in particular, galactomannan gums, when added to an aqueous solution as a powder have a tendency to "clump". If the gum is soluble these clumps will gradually disappear together with any temporary haze which might be observed.
- the Cassia alloy gum compositions of the present invention appear to have a significantly decreased tendency to form clumps compared to the gelling and thickening agents alone. This increased dispersion ability has been observed in particular with Cassia alloy gum compositions containing xanthan, algin, gellan, hydroxyethylcellulose and polyacrylamide. This property provides an added utility for the Cassia alloy gum compositions.
- An additional unanticipated property is the high water absorptivity of solid Cassia :xanthan alloy gum compositions whether in the form of a powder, a fibrous coprecipitate or as a continuous film.
- a 50 ⁇ :50 ⁇ Cassia :xanthan alloy gum powder (about equal parts by weight) has been found to absorb up to 1,0 ⁇ 0 ⁇ 0 ⁇ times its weight of distilled water and, according to an external evaluation, the dry fibers absorb 50 ⁇ times their weight of human urine, compared with 25 times the weight absorbed by a starch-polyacrylamide graft copolymer used as a control.
- the solid Cassia alloy gum compositions of the present invention can be coprecipitated or separated from the aqueous extract by any convenient method.
- carrageenan is the gelling and thickening agent
- the Cassia alloy gum composition can be precipitated with potassium ions (KCl).
- KCl potassium ions
- any alloy gum composition can be coprecipitated by evaporating the aqueous medium or by adding a water-miscible organic solvent to form a precipitate or coagulum which can be separated from the liquid by filtering or centrifuging.
- Isopropanol is the preferred water-miscible solvent.
- the coprecipitated wet homogeneous solids can be dried in a vacuum or with hot air.
- an aqueous extract of Cassia gum was prepared by adding 1.0 ⁇ g of Mucilose 39H (Diamalt AG, Kunststoff) Cassia meal to 10 ⁇ 0 ⁇ ml of water, the mixture stirred and brought to boiling using a microwave oven. After heating for 1 hour at about 85°C, 2.5 g of filter aid was added, the mixture stirred to completely disperse the filter aid, then pressure filtered (0.24mPa; 20 psi) through filter paper. The filtrate (85 ml) was combined with a 25 ml hot water wash.
- the extract was precipitated by adding twice the volume of 99% isopropanol (2-propanol) with stirring.
- the coagulum was collected by filtration through a nylon cloth, squeezed, then suspended in 10 ⁇ 0 ⁇ ml 80 ⁇ % 2-propanol (aq.) as a wash, collected, then dried in a 60 ⁇ °C forced-air oven, ground to 40 ⁇ mesh to yield 0 ⁇ .34 g of a tan powder, (34% yield).
- 10 ⁇ 0 ⁇ mg was dispersed in 10 ⁇ ml of distilled water and heated to boiling, a light brown mass of swollen particles in a viscous solution was observed by examining with an oblique light. Upon standing, this material developed an opalescent haze, which could be attributed to a coating around the swollen, undissolved particles.
- the Breakforce Value is the numerical value given for gel strength. In determining gel strength, the gel is cast in a 70 ⁇ x 50 ⁇ mm crystallizing dish, then the dish containing the gel placed on a scale. A plunger with a 1 cm2 area is driven electrically into the gel at constant rate. The value recorded on the scale at which the plunger breaks through the surface of the gel is the Breakforce Value (gel strength) and reported as g/cm2.
- Solidizing Effect is determined by comparing the light scattered by a solution or gel of Cassia gum alone and an equivalent alloy gum. Usually a range of alloy gum compositions is employed of 25:75, 50 ⁇ :50 ⁇ and 75:25 by weight. Results are reported on a semi-quantitative scale of strong, medium and weak.
- An aqueous extract of Mucilose 39H extract was obtained by heating a 2% slurry in water at about 90 ⁇ °C for two hours, then filtering. A filtrate containing 0 ⁇ .71% 2-propanol insolubles and a 90 ⁇ °C viscosity (Brookfield) of 25 mpa.s was obtained.
- the carrageenan used was a plant extract containing 2.42% 2-propanol precipitables, 30 ⁇ mpa.s viscosity. This and the Cassia extract were combined to form five gum compositions which were coprecipitated (1:4) in 3% KCl (aq.) and the Cassia alloy gum recovered.
- the dry powder and the dry coagulum fibers of the 50 ⁇ :50 ⁇ Cassia :xanthan compositions were extremely water absorbent, with the powder taking up 1,0 ⁇ 0 ⁇ 0 ⁇ times its weight of distilled water (forming a clear swollen particle mass), less of 1% NaCl (aq.) - showing ionic strength dependency.
- aqueous compositions were produced in weight ratios of 75:25; 50 ⁇ :50 ⁇ and 25:75 of Cassia gum and other gelling and thickening agents. Results are presented as Table V. Cassia alloy gums were precipitated with isopropanol unless otherwise indicated.
- Solubilizing effect summarizes in semi-quantitative terms the solubility of the Cassia gum alloy compared with the Cassia gum alone.
- Gel synergy is considered to be present if the gel strength of the alloy gum is greater than the individual gums. As some gums do not form a gel (gel strength is zero) the gel synergy is reported on a semi-quantitative scale.
